In determining the qualifications necessary for registration under the provisions of this subchapter, the Board shall not accept national and/or state certificates in lieu of the examination administered by the Board of Examiners for Podiatry in the Virgin Islands. However, where there is a documented need for the specialty or its subspecialties as determined by the Medical Directors of the hospitals or the Commissioner of Health, the Board is authorized to grant without examination a special unrestricted license for a three-year period. A special unrestricted license shall be issued only to a Podiatric physician who has an unrestricted license to practice in the United States, and who has completed an accredited residency program approved by the American Podiatric Medical Association.
